A Method of Error Compensation for Multi-Linear Structured Light Probe

摘要：

Aiming at the problem of un-equivalence and un-parallelism of light stripes in the measuring system based on multi-linear structured light, the method based on triangular standard piece is presented. When multiple light stripes are projected on the slant of a triangular standard piece, the information of un-equivalence and un-parallelism of light stripes can be converted into the light plane which can be captured by CCD and computed by trigonometry. According to the obtained error data, the appropriate scanning distance is selected to scan objects. After reconstructed, the 3D data are corrected and combined. An example is given to prove that presented method is effective.
